String decryption for blizzard's string encryption, tested on specifically overwatch, if you make any improvements, open a PR.
Note that this is a python script is for IDA Pro.
I will under no circumstances provide support for you, the script is provided as is.
I have not tested this on other blizzard titles, the patterns may not be the same, so if you want to use it on another game, you may have to change them.
